Brave new WAN: Technologies emerge to transform wide area networks

Share this item with your network:

In the blink of an eye, the formerly staid wide area network has become a brave new world, defined by rapid change and innovation, and the subject of plenty of industry buzz. Emerging WAN technologies -- from software-defined networking to cloud -- are transforming how IT pros build and manage their branch networks.

The shift comes at an opportune time. As the proliferation of mobile devices, a rise in the number of remote workers and an escalating demand for bandwidth put increased pressure on the wide area network, network managers must find creative ways to increase flexibility and agility while keeping costs in check. The new WAN technologies help them do just that.

In this special edition of Network Evolution, we explore how network managers can use emerging WAN technologies -- including software-defined WAN, cloud networking and next-generation firewalls -- to create networks that keep pace with enterprise needs ... without breaking the bank. Also in this issue, we'll take you on a tour of three enterprise networks currently using SD-WAN, and explore how to keep a hybrid WAN secure.
